Hill is a corrupt politician elected mayor of Gotham City thanks to the machinations of Rupert Thorne. He became mayor in Detective Comics #511. During his early time in office, he assisted Thorne's attempts to identify and defeat Batman, principally by firing Police Commissioner (and Batman ally) James Gordon and replacing him with one of Thorne's cronies, Pater Pauling. After Thorne was defeated, Hill re-instated Gordon but spent the rest of his time in office trying to shift the blame for the state of Gotham onto Gordon's shoulders. Hill last appeared in Batman #381. From Wikipedia.com
